Is there any way to disable the "the compile flags have changed, recompile everything" check? I want to built with another prefix than installing to create a tarball I copy to other machines. Is there any way to do this? Otherwise: could we include something like this?

ifeq ($(IGNORE_CFLAG_CHANGES),)
# old GIT-CFLAGS rules
else
GIT-CFLAGS:
        touch "$@"
endif
